l,26,335., Patented Apr, 16, 1918 My iuvcntionrolatos to type forms and slugs rules thorofor on i also to a method of securing the rules and slugs'togcohor in typo form?" and tho soil; is to gsrovidc. simple slugs and rulcs which will be onto musically locked in operative position duri tho planing operation. Gus of ihe obit to Q3? v'ido rules which w ll be sol o-oking. The various lugs 01 5 ions o... ngs f'r holding the rules in .09 are dis- 2. had with and the various matrix. moldmg devices for moldings slugs with such projections are dispensed wilvh and much expense is avoidoc. Other objects and advantagos will be fully oxplainod in the following doscripiion and the invention will bo more porLiculsrly poinfiod out in the claims.

Rsforencc is had to the accon'ipsnyn drawings which form, a. part of this :ippiico" tion;

Figure 1 is a pcrspoctivo view of a typo form constructed in uccordsncc with my vcntion. Fig. 2 is perspective View, showing the method of fastening the rules and slugs together, tin-co rules being shown in section and placed in the grooves in the slugs above the quad line with their printing edges extending sufficiently above the level top surface. of the printing characters, so that when plzmcd or pounded down into the slot the bottom edges of the rule will undoroutinto the metal, and three rules being show-7n in. section after they have been pressed down in. the grooves and the edges of tho rules pressed into llile metal of the slugs. Fig. 3 is a. perspective View of a slug, showing a groove for receiving a rule.

Fig. l shows a broken. slug with leader line thereon, a groove for receiving and holding a rule. 5 is :1 broken perspective iew of ablank slug with projections thereon for holding the rule in place when the rule has been planed or pounded down love]. with {specification of Letters Patent.

printing surface of the W no-form and is iniendcd for wide spacing of figure columns.

Similar charsctors or reference are used I indicaizciho some parts throughout the several viows'y I l The drawing, show use improved rules in onlsrgsd rich s and rules for different purposes are shown. Sclf loclzing rules are provided for .zrll kinds ofmbulotcd and ruled blank forms or blank work. Slugs l of standard equipment size are provided, and these slugs lmvorectongular grooves 2 across the slugs to receive the rules, the grooves extending from the quad base upwardly. Rules 3, 4, and 5 are shown in the type-form in F 1. The grooves 52 are made between the typo as shown in Fi 1 and 3 {LllfilllllOllgll the longitudinal rib for leaders and horizontal ruled lines, as shown in Fig. l, or through any other 15100- jcciion on 2% slug :ibovo the quad liris; A blank slug may be provided with. upstanding projections 6, as shown in. Fig. 5, for holding the rules in place in widely spaced columns to start theucuated edges 7 down into the metal as hereinafter described.

The slug shown in Fig. 2 is for illustrm tion of the method of iastcningthorules and not for-illustration of type or printing characters. Rulo 3 is for -the light vertical line printing. Rule 4; is for heavy vertical line. priming. and rule 5 is for the double vertical line printing. The three rules'aro bifiuroatcd in tho loasc and-the bifurcation is so made thatv the .two bottom edges aroacir' lied and slightly curved outward. j-Thethroe rules to tho left of'Fig. 2 are just lyingloose in the grooms 2 and attention is called to the fact they project above the type level and remain in. this position until thstype and rulo is planed or pounilod'down. W'hon tho planer is placed on the. type and hammorcd down, the siizrrpcncd or aouotcd edgesof the rules will bo pressed downward and spread laterally into the metal of the slugs and. the three rules to the right side of Fig. 2 show how the acuated edges 7 of the rules have been pressed downward and laterally into rho metal and the top of the rules are brought to the. type levol. When the edges of the rule are forced down into the metal, they will be curved as shown on the right side of Eig. 2. The rules are thus sutomaly messes ically loclte'd in the slugs and need'no other '1. A type-form including slugs and rul-.

ing members, said ruling members having a printing edge. and acuated base edges which are adapted to penetrate the metal of the supporting slug and to be spread as they are driven into the type of the slug for anchoring the rules to the slug.

. 2. A metal printing rule for type forms having the base edges of the rule acuated and adapted to penetrate the metal of the slug and to be flared as they are planed into the metal of the slugs of the type form forself locking of the rule to the slug.

3. A metal printing rule for type forms having the base edges thereof adapted to be spread and driven into the metal of the slug of the type form below the quad line thereof when the rule is planed down.

4. A type-form provided with ruling members, each ruling member lying on the quad base of the supporting slugs between the type thereof and having a bifurcated base the edges of which are adapted to penetrate the metal and to be flared as they are laned, into the metal of the slugs for lockmg the slugs and rules into a type-form.

5. A type-form composed of slugs having transverse grooves extending down to the quad lines and ruling members placed in said grooves and having bifurcated bases the edges of which are acuated and adapted to penetrate the metal of the slug and to be spread as they are planed into the metal j of the slugs for anchoring the ruling mem- 40" her to the slug,

6. A metal printing rule for t pe-forms to be placed on the quad line 0 printing slugs and having a bifurcated base the edges of which are acuated and adapted to spread and undercut their way into the metal of the slug when planed down on the slug for automatically locking the rule to the slugs, 7. A ty e-form composed of slugs of type metal an rinting rules of harder metal laced on t e quad line of the slugs and aving a base provided with acuated edges adapted to spread and'penetrate their way into the metal of the slugs when the rules are planed down.

8.A type-form composed of slugs provided with printing characters and transverse grooves between said characters and ruling members placed in said grooves and having acuated-edges adapted when planed down to undercut their way into the metal of the slugs for locking the ruling members and the slugsinto atype-form.

9. A type-form composed of slugs having level top surfaces and printing characters rising from said surfaces and transverse grooves between said characters extending to the quad line and ruling members placed in said grooves and provided wth acuated edges adapted to cut into said slugs, said edges being adapted to be curved in the metal of the slugs below the quad line thereofl 10. The herein described method of form ing a type form which consists in placing printing rules across printing slugs and planing the rules down until the. printing edges of the rules are on a level with the type level of the slugs and simultaneously forcing the edges of the rules to undercut their Way into the metal of the slugs for anchoring the rules to the slugs.

11. The herein described method. of pre paring a type-form which consists in assemling slugs and ruling members across the slugs and locking the rules to thoslugs by forcing portions of the rules to cut their Way into'the metal ofthe slugs for anphoring the ruling members to the slugs.

12. The, herein described method of pre paring type-forms which consists in assembling prepared slugs and prepared ruling members across the slugs and planing the slugs and ruling members and forcing portions of the metal of the ruling members to cut then Way into the metal of the slugs.

13. The herein described method of preparing type-forms which consists in assemthe printing characters and simultaneouslyforcing portions of the ruling members into the metal of the slugs.

In testimony whereof I set my hand, this seventeenth day of December, 1917.
